America's Relationship To The Natural World

A special hour of Radio Boston, looking at the deep and complicated history of the relationship between Americans and the natural world. We check in on the Mystic River clean-up, take a kayak journey across the North Shore's Great Marsh, and explore how our relationship with nature is portrayed through film and what that tells us about our values.
